Abstract: A display device according to an embodiment includes a light emitting unit including a first light emitting diode to emit first blue light, a second light emitting diode to emit second blue light, the second blue light being different from the first blue light in central wavelength, and a quantum dot color conversion unit including a quantum dot color conversion layer on and overlapping the second light emitting diode.

Abstract: A brake apparatus for vehicle may include: a caliper body, a drive unit connected to the caliper body and generating a rotational force, a transfer gear engaged to the drive unit and transferring the rotational force generated by the drive unit to a piston unit engaged to the transfer gear, a first parking unit rotated together with the transfer gear, a second parking unit movably mounted on the caliper body and, according to a direction of a movement of the second parking unit, selectively interfering with a rotation of the first parking unit, and an adjustment unit mounted to be spaced away from the second parking unit, and) configured for adjusting the direction of the movement of the second parking unit.

Abstract: A brake apparatus for a vehicle may include: a drive unit configured to generate a rotational force in forward and reverse directions, a piston unit configured to be moved forward and backward in conjunction with the rotational force generated from the drive unit, a transfer gear unit configured to transfer the rotational force generated from the drive unit to the piston unit, a parking gear unit configured to be rotated together with the transfer gear unit, a locking unit arranged in a manner that faces the parking gear unit, fastened to the parking gear unit when braking for parking is performed, thereby limiting a rotation of the parking gear unit and an unlocking unit separating the parking gear unit and the locking unit from each other when the rotational force is generated in the reverse direction from the drive unit.
